DPI Checker

DPI Checker estimates physical print size from image resolution. Given pixel width, height, and a target DPI, it computes print dimensions in inches and centimeters, enabling early assessment of asset readiness for posters, brochures, or packaging. It is useful for photographers, designers, and production teams who need objective size guidance without trial-and-error resizing.
Core calculation uses DPI = pixels / inches; inches = pixels / DPI; then convert to cm. The tool accepts three inputs: pixel width, pixel height, and target DPI (positive integers). Outputs include print size in inches and centimeters for both axes and a signal indicating quality fit against the target DPI. Optional options estimate the recommended DPI for a desired print size.
Unique value lies in immediate, bias-free calculations that support both landscape and portrait assets, reducing rework across creative workflows. Use cases include prepress validation, asset scoping for ad campaigns, and client proofing. The tool remains non-destructive and does not modify images, while providing clear guidance on whether a given DPI will meet standard print quality.
